摘要:支撑板弯曲零件的模具设计
对一种大型U 型工件的折弯成型模具的设计和试模以及模具的改进过程, 阐述了这类材料弯曲成型模具设计的方法, 并从中总结出了对于类似模具设计过程中应注意的事项。??
此次毕业设计属于冷冲压模具,设计课题为下端盖切口弯曲模具支撑板弯曲模设计?不是这个题目吗?
,模具工序由斜刃冲裁和弯曲组成。冲压工件为下端盖半成品,之后在半成品上冲出六??
个大小不完全相同的孔并压弯。由于为圆形件,并且切口中心对称,所以并不需要排样和计算压力中心。模具为倒装复合模,工件开始放在定位板上,冲压完成后工件从上端由推件装置推出。上模为凸凹模起冲裁凹模和弯曲凸模作用;模具中定位板起定位和弯曲凹模顶件装置两种作用;六个凸模用环氧树脂浇注固定在下模上,起冲裁凸模和弯曲凹模作用。定位板由弹簧作用与凸凹模分开,由安装在压力机上的气垫推动卸料螺钉带动定位板向上运动,与凸模分开并方便工件放入。

Abstract: The bending char acter ist ics are dif f erent between high str ength stainless steel andlow st r ength??
metal mater ials. Th rough design, test and improvement processes of a bendingdie for a k ind of large U􀀁type part ?
, the design method of bending dies in such kind of mate􀀁rials?
was i llust rated, and some matter s need attent ion during design process of similar dieswer e also is this cold stamping die design issues for the next Cover incision bending dies Die processes by bevelled punching and ponents. Stamping parts for the next semi-Cover, after the last out in the semi-6 size is not exactly the same hole and bending. Because of the round pieces, and center symmetry incision, there is no need for nesting and calculated pressure center. Die for posite mold, started on the workpiece positioning plate, stamping pletion of the workpiece from the top by pushing the device launched. On the scale of punch and die with punching and bending die punch; Die positioning pulled positioning and bending Die top two pieces of equipment; 6 punch with epoxy fixed on the next model, since blanking punch and bending die role. Positioning plate by a spring with the role of punch and die separately, by the installation of the press in promoting the discharge air cushion screw driven positioning plate upw
ard movements, punch and separate the workpiece Add convenience.
